Dear Sergio,

The implementation of NOMA in our simulator is based on the 3GPP MUST scheme in which the farUE is limited to QPSK modulation. The scheme is to be used such that a strong cell-center UE is coupled with a weak cell-edge UE that cannot transmit with high rate anyway to begin with.

If you switch to OMA, and let the transmit power of the BS increases, then sure, at some point the farUE will no longer be weak (since it now has very high SNR), and then it would comfortably switch to high modulation orders and code rates, hence, resulting in a higher throughput.

Best,
Bashar
